IMPROVEMENT IN MARKING-ATTAUHMENT FOR SEWING MAGHINES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, R. H. ST. JOHN, of Belle'fontaine, in the county ofLogan, and State-of Ohio, have invented'a new and improvedMarker-Attachment to Sewing Machines, for quilting, tucking. ctc. and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of thisspecification. v

The present invention relates to an attachment for sewing machines forthe, purpose of marking the cloth at the points where it is to be foldedfor tucking, quilting, or for any other purpose, the attachment embracedin the present invention being so attached to the resser-foot or anyother suitable part of the sewing machine,

and being so constructed as to be operated by the necdlc-bar, as theneedle which it carries passes down through the cloth in a manner aswill be hereinafter described, reference being bad to the accompanyingplate of drawings, in which- Figure 1 is a plan or top view of theattachment for marking the line of tucks applied to the pressure-foot of-a sewing machine, and i i i i Figure 2 a rear elevation of one side o'fthe same.

Similar letter'sfof reference indicate like'parts.

A, in the drawings, represents the resser-foot of the sewing machine, towhich a holder, B, is attached in any suitable manner, ,it being shownin the present instance as placed in and between the two prongs or armsC of the resser-foot. This holder B is provided for the attachment ofdevices constituting the present invention, for marking the line atwhich the cloth is to be folded to'forrn a tuck in it, or to be quilted,etc. Through the holder B, in a direction at right angles to the lengthof the presser-foot A, or in other words at right angles to thedirection in which the cloth' passes through the machine to theneedle-bar, extends a horizontal shaft or spin 10, E, turning insuitable bearings of the said holder, formed in its two parallel uprightarms or ieces F, and provided at one end, G, with a curved arm, H,suitably sharpened at itsouter end I, to form a crease or indentation,as it were, in the cloth without cutting or severing or in any othermanner injuring'its fibres or threads. To the spindle E, between theuprights of the holder, is secured by a set-screw, J, a dog orfoot-piece, K, made of a curved shape, and eiitending over the top ofthe resser-foot into the same vertical plane as the vertical movement ofthe needle-bar, so thatwhcn such bar is depressed it will strike againstthe same,

'and thus through it turn the spindle E to which it is securedsufficiently to bring the marking-arm of such 'spi'ndle to and down uponthe cloth for marking-or indenting it.

i From the description above it is plainly bvious that as the clothbeing served passes through the machine the needle-bar, every timeit'descends to carry its needle through the cloth, acts upon'the dog orfoot-piece K in the manner explained, thereby causing the said cloth tobe at regular points of its length marked, as it were,

in a continuous line, or, nearly so, parallel to the line of thestitches being made in the cloth, by which line the cloth can be foldedto form another tuck in it, when, as it is sewed, the line of the nexttuck is similarly indicated, and so on, as long as may be desired, oraccording to the extent of the cloth.

To adjust the marker to any width of tuck within its ezitent, it is onlynecessary to unscrew the set-screw J and slide thespindle through theholder and dog or foot-piece K, either more or less, according as it isdesired to mark a wide or narrow tuck upon the eloth, and there secureit by tightening the set-screw J.

To prevent any undue strain upon the tuck-marking attachment by theneedle-bar, I have secured to the surface of the dog or foot-piece K,against which the needle-bar acts, a hentspring, M, which spring, incase of any obstruction or for any other cause,-yields, as it were, andthus relieves the ,marking-attachment of any strain without interruptingthe downward'movement of the needle-bar, as is obvious.

In lieu of attaching the marking device to the Presser-Toot of thesewing machine, it may be secured to any other suitableiportion of themachine so long as it canbe operated by the needle-barin the mannerexplained.

And furthermore, the marking device may be used forpther purposes otherthan marking the line of tucks, as,

for instance, for quilting, etc., and therefore I do not intend -tolimit myself to any one use of the same in connection with ase'wingmachine.

What I claim as new, and desire to secure by Letters Patent, is- Thespindle E,'having dog or foot-piece K, marker H, spring M, screw J,holder B, and presser-foot A, when constructed and arranged as hereinset forth for the purpose specified.

Thcabovc specification of my invention signed by me this 8th day-ofOctober, 1866.
